You might encounter situations where buttons or signs are not visible or clickable. This usually takes place when there is changed information on the web page, such as the change of UI or status after a firmware update.
To speed up access, the browser will store the information of the web pages that users frequently visit in the form of cache. If the browser does not request data renewal from the server, you might find yourself seeing different layouts or status on the same NAS web UI, or having trouble clicking on some buttons.
We suggest that you change a browser or try cleaning up the cache on the browser before re-connecting.
